INGOT-MOLD Patented Nov. 3, 1908.

Application filed November 1, 1907. Serial No. 400,212.

To all whom it may concern.-

Be it known that I, HARRY M. GRAY, a citizen of the United States residing at Pittsburg, in the county of legheny and State of Pennsylvania, have invented certain new and useful Improvements in Ingot-Molds, of which the following is a specification, reference being had 'therein to the accompanying drawing.

My invention refers to an im roved ingot casting mold and it has for its 0 ject to provide a mold for casting steel or any other metal in ingot form, so as to produce an ingot hayinglparallel walls, and to cheapen and simplify t e casting. The mold comprises an outer shell having inner relatively mov- 1 able walls ada ted to be raised andseparated within the she I to release the in at for stripping in the manner hereinafter ascribed.

r In the drawingsz-Figure 1 is a vertical sectional view through one form of ingot mold indicated by the line I, I, of Fig 2.

Fig. 2 is a plan view of Fig. 1. Fig. 3 is a sectional view similar to Fi 1, but showing the interiorwalls of the mol raised and separated to release the ingot. Fi 4 is an end view in elevation of Fig. 1. Fig. 5 is a plan view similar to Fig. 2, showing a modified arrangement of the interior relatively movable walls. Fi 6 is a perspective detail view showing t e construction of the wall used with the arrangement shown in Fig. 5. Fig. 7 is a similar erspective view showing the construction 0' the wall used with the arrangement shown in Fi 5.

' 2 is the outer shell of the mold of suitable form and dimensions to inclose the inner movable walls and to provide an interior cavity for the ingot.- In the form shown in 40 the principal figuresof the drawings the "oposite inner faces 3 of shell 2 are tapered or inclined upwardly and outwardly, providing inclined seats or bearings for the inner movable sections 4, 4, the outer faces of which I contact with said faces 3 and are of the-same degree ofslope. The sides 5 of sections' i may abut directly against each other or overla as indicatedat 6, to provide a tight joint ,w an the inner sections are in their ldwer ,50 position, as in 1, for pouring.

At their upper ends sections 4 are rovided with eyes 7 or an other suitab e lifting mechanism by whic 1 the sections may be simultaneously raised b a crane and its connections S of any suita' le construction, while each of said sections 4* is also provided with lifting pins 9, secured in their body portion and prof'ecting outwardly through slots 10 in the wal s of outer mold casing 22, as clearly shown, retaining ins or other devices 11 being provided if esired. By this c0nstruction, after the mold has been set upon its base, as in Fig. 1, w'ith sections 4 depressed to the lowermost position and the inner walls thereof having approached each other, the metal is ppured into the interior cavity, and when su 'cie'ntly cooled, sections 4, 4, are raised, as indicated in Fig. 3, and due to the inclined faces 3 and the corresponding outer faces of sections 5 abutting thereon, sections 4 are caused to separate outwardly away from contact with the ingot A, leaving 1t resting upon the base, and upon continuous raising by the crane, pins 9 come into contact with the upper ends of slots 10, whereupon the outer mold 2 and the entire apparatus maiy be bodily lifted away from the'mgot.

n Fig. 5 I have shown a construction wherein the inner sections 4 are L-shaped, and provided on both sides with tapering faces ada ted to contact with correspondingly tapered aces around the inner four walls of the outer mold 2, said sections 4 being also provided with lifting eyes 7, preferab y located at their corners to e ualize the Weight.

B this construction it wil be seen that'upon v li ting sections 4 they will recede away from the ingot at all sides thereof, each section traveling outwardly toward the direction of its corner, each section separatin in corresponding opposite directions. ith either construction the release of the ingot and the avoidance of a frictional contact between it and the inner mold faces, results in an immediate stripping without the necessity of the employment of any additional force, so that the mold is easily and readily withdrawn, the ingot retaining its position byl-the more force of gravity. I T

't is desired tn reverse. the ingot mold,

the pins 9 may be extended upwardly sufficiently far to serve as trunnion bars, and mounted in bifurcated extremities 12 of a suitable support, as indicated by dotted lines of Fig. 4. By this construction the entire mold may be raised or lowered and manipulated and also reversed if desired, for the purpose of solidifying the metal of the ingot after casting. I

It will be understood that the mold may be made in any desired form, size, or cross section, and it will be found to give the desired results in ractice, avoiding the objection able sticking oFthe ingot.

Changes or variations may be made by the skilled mechanic in various features without departing from the invention as covered by the following claims.

What I claim is:

1 An ingot mold having interiorly tapered walls and inner sections having tapered faces seated thereon and adapted to be moved and to recede outwardly, substantially as set forth. v

2. An ingot mold consisting of an outer shell having inner longitudinally taperin faces, and a plurality of separable assemble lining sections having corresponding tapered bearing faces.

3. An ingot mold consistin of an outer shell having inner longitudina ly oppositely taperin faces, and a pluralit lof separable assembfed lining sections-'havin" corresponding oppositely tapered bearing aces.

shell ha g 4. An ingot mold consisting of an outer tially as set forth.

5. An ingot mold consisting of an outer inner longitudinally tapering faces and provided with lining sections having abutments adapted to engage and lift the outer shell after preliminary raising, and means for lifting said sections, substantially as set forth.

6. In an ingot mold, the combination of an outer shell having inner longitudinally tapered faces and oppositely arranged slots, inner molding sections havm correspondingl tapered bearing faces an provided wit studs extending outwardly through said slots, and means for lifting the sections, substantiallyas set forth. 1

7. In an ingot mold, the combination of an outer shell having interior diverging bearing faces, and interior lining sections having corresponding faces and arranged for movement longltudinally of the mold cavity and for separation from each other.

In testimony whereof I afiix in presence of two witnesses.
